AI Technical Summary

Technical Problem

Existing wind power generation systems are prone to overload under high wind speeds. Mechanical braking leads to increased energy loss, and adjusting the blade angle requires precise control with untimely response, affecting system efficiency and safety.

Method used

The wind speed is detected by sensors, and the speed is adjusted by blowing air into the fan blade assembly using an air compressor and air tank system. This includes deceleration and acceleration mechanisms. The control system uses a control valve assembly and a timer solenoid valve to achieve automatic adjustment of the fan blade assembly speed.

Benefits of technology

It reduces mechanical wear and maintenance costs, improves system efficiency and reliability, extends service life, and enables continuous power generation at low wind speeds. It also protects the device from impacts by flying organisms and reduces energy loss.

Abstract

The invention discloses a wind power generation device and a wind power generation control method.The wind power generation device comprises a supporting column, a sensor and a wind power generation mechanism, the wind power generation mechanism comprises a generator and a fan blade set, the wind power generation device further comprises a speed reduction mechanism, the speed reduction mechanism is electrically connected with a control system, and the sensor is electrically connected with the control system; when the sensor detects that the external wind speed reaches the first preset value, the control system controls the speed reduction mechanism to blow air to the fan blade set, speed reduction is conducted through blowing, a braking speed reduction structure does not need to be additionally installed between the blades and the generator, and therefore mechanical abrasion and maintenance cost are reduced; a complicated mechanical braking speed reduction structure is not arranged, so that the design of the wind driven generator is simpler, the weight is lighter, and the installation and the maintenance are more convenient; and mechanical parts are reduced, so that the reliability of the whole system is improved, potential fault points are reduced, and the service life of the wind driven generator is prolonged.
